I would like to begin with something positive, and there is a lot of positive things, but by all the gods... my finger hurts so much. I would recommend to add auto attack.
Beside my finger, I enjoyed this game. The learning curve is brilliant. Graphics, sounds and effects are awesome. The theme? Wait for a few seconds and you will see that chaos :D
But still, I miss some huge VFX and SFX when player dies :/
